Test-driven development using Red-Green-Refactor for bug fixes, new features, and regression prevention. Writes a failing test first to prove a defect or define behavior, then implements minimal code to pass, then refactors. Use when fixing bugs, encountering failing behavior, adding new features, writing tests, or when the user mentions TDD, red-green-refactor, regression test, failing test, test first, or test-driven.
Unified testing skill — TDD workflow, unit/integration patterns, E2E/Playwright strategies. Replaces tdd-workflow + testing-patterns + webapp-testing.
Use this skill when deciding what to test, choosing between test types, designing a testing strategy, or balancing test coverage. Triggers on test pyramid, unit vs integration vs e2e, contract testing, test coverage strategy, TDD, BDD, testing ROI, and any task requiring testing architecture decisions.
Backend API 전문 생성 스킬. "백엔드 만들어줘", "API 생성", "서버 코드 만들어줘" 키워드로 트리거. TDD 검증 필수, AI와 티키타카로 완성도 확보.
Enforces TDD (Red-Green-Refactor) for Rust development. Auto-triggers on implementation, testing, refactoring, and bug fixing tasks. Provides Rust-idiomatic testing patterns with anyhow/thiserror, cfg(test), and Arrange-Act-Assert workflow.
Expert knowledge of testing Node.js and Express applications including Jest configuration, Supertest for API testing, unit vs integration vs e2e testing, mocking external APIs, test organization, code coverage, CI/CD integration, and TDD practices. Use when writing tests, setting up testing framework, debugging test failures, or adding test coverage.
Write, review, or debug end-to-end tests using Playwright. Use when asked to 'write e2e tests', 'add Playwright tests', 'test this user flow', 'fix flaky tests', 'create a test suite', or 'debug this e2e failure'. Invoke with /playwright-e2e or when user mentions e2e tests, Playwright, or test automation. Do NOT use for live browser interaction via MCP tools — use playwright-mcp for that. Do NOT use for unit/integration tests — use tdd-guide agent instead.
Auto-generate project workflow config (docs/workflow.md) from existing PRD and CLAUDE.md with zero questions. Use when user says "set up workflow", "configure TDD", "wire up dev workflow", or after running /scaffold before /plan. Do NOT use for founder setup (use /init) or project scaffolding (use /scaffold).
TDD Skill for Team Workflows (Phase 3). Before writing any implementation code, you must first write a failing test and verify the failure, then write the minimal implementation until it passes, and finally refactor and re-test.
LOAD THIS SKILL when: implementing new features with TDD, user mentions 'TDD', 'test-first', 'red-green-refactor', 'failing test', or when building Effect services that need thorough testing. Covers TDD methodology, Red-Green-Refactor cycle, Effect service testing with mock layers, and test-first development workflow.
Autonomous PRD implementation loop — turns GitHub issues into shipped code using TDD, code review gates, and Docker sandbox isolation. The execution engine for the grill-me → write-a-prd → prd-to-issues → ralph pipeline.
